Voted. Nice format btw. I love playing Sumari since it's just a big map of fatal funnels. It usually comes down to who can hold corners and who can breach using teamwork. A close second is the recent update for al basrah. I see it as an expanded concept of sumari but for mechanized tactics.

Voted, Sumari is probably my top pick due to how much CQC takes place, really makes SL'ing hard when you don't want to push your whole squad down 1 alley. Grenades are pretty much instant killers in the tight corridors and small compounds that this map has.
